They seem way too flimsy for 40 ft.lbs. Is there a published value? If not, any advice? | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | Quite honestly, I usually throw them away.

If so the shop manual says to turn them down until they touch then 1/2 turn more.

Well it is a bit of a mystery why they were used in the first place. I did use the "pal nuts" on my 216 though. You basically snug them and then turn a bit more. I don't actually think they are needed. | | | | | Joined: Mar 2008 Posts: 54 Wrench Fetcher | | Wrench Fetcher Joined: Mar 2008 Posts: 54 | It's a 261. It had the nuts on the rod cap nuts when I removed the rods. Maybe the PO put them on? Does a 261 not normally have them? | | | | | Joined: Mar 2008 Posts: 54 Wrench Fetcher | | Wrench Fetcher Joined: Mar 2008 Posts: 54 | It is a stamped steel nut, but the 261 manual doesn't mention them. I am beginning to think they shouldn't be there on a 261. | | | | | Joined: Mar 2005 Posts: 1,636 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,636 | My 261 does not have them. Just regular rod nuts. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | I believe 1954 was the last year to use these.
